Title:
EASY TO OPEN ZIPPER TAPE, AND PACKAGING BAG WITH EASY TO OPEN ZIPPER TAPE
Document Type and Number:
WIPO Patent Application WO/2011/049089
Kind Code:
A1
Abstract:
A linking part (613) is disposed between a first thick part (612) and a second thick part (613) upon a cut part (7). A minimal thickness part (66) is additionally disposed upon the linking part (613), such that stress may be concentrated upon a single site. Consequently, when a substrate film (24) of a bag is pulled apart, the linking part (613) is capable of guiding a cut line toward the minimal thickness part (66), and of setting the location of the cut line to the minimal thickness part (66), allowing ease of opening and closing.
